High Yield ENT COPY Flashcards
A 22-year-old presents to the GP with difficulty breathing through his nose following a fistfight. During the fight, he sustained a blow to the face and fell to the ground, but denies losing consciousness. He has not experienced any vomiting or any other symptoms, except for difficulty breathing through his right nostril. On examination, there is a bruise around the right cheekbone and a red swelling arising from the right nasal septum.
What is the next most appropriate management?
Routine referral to ENT
Urgent referral to ENT
Follow-up in 1 week
CT head
Conservative measures i.e. cold compress
Urgent referral to ENT - nasal septal haematoma → needs urgent evacuation under GA w/ packing +/- suturing
causes of epistaxis
Causes include trauma, insertion of foreign bodies, bleeding disorders, angiofibroma, cocaine
Presentation = nose bleeding (usually unilateral), can also be vomiting
blood supply to the nose
Anterior
Most common
Nasal septum
Littles area (kiesselbachs plexus)
Posterior
Nasopharynx
Woodruff plexus
summary of management of epistaxis
Management
1. Position change and pinch for 20 mins
1. If bleed visible – silver nitrate cautery, if not – anterior nasal packing
1. If haemodynamically unstable or bleed not visualized admit to hospital
1. Sphenopalatine ligation in theatre
why can cocaine cause nose bleeds
cocaine is a powerful vasoconstrictor and repeated use may result in obliteration of the septum.
why do we always need to exclude septal haematoma
Septal necrosis + nasal collapse if untreated
presentation of septal haematoma
- Nasal obstruction, pain, rhinorrhea
- Boggy swelling, soft & fluctuant palpation, asymmetry of septum w/ swelling
complications of septal ahematoma
septal abscess, septal necrosis + nasal collapse (saddle nose)
manaegemnt of septal haematoma
Mx by aspiration or drainage, suture, packing, Abx
- No need for XR if simple nasal # - cartilaginous injury won’t show & radiographs won’t alter Mx
- Ideally seen by ENT 5-10d post-injury
- Re-assess for deviation after 7d once swelling subsided – septoplasty 12m post-injury
- Only intervene if cosmetic deformity or nasal obstruction
- Needs reduction within 14d
A 6-year-old boy presents to the GP with his parents. He had a tonsillectomy 6 days ago and is recovering well, but they are worried after finding spots of blood on his pillowcase this morning. He has no other significant medical history. On examination, the boy appears well with no active bleeding, and observations are within normal limits.
What is the next most appropriate management?
Reassurance & discharge
Conservative measures i.e. cold compress
Routine referral to ENT
Urgent referral to ENT
Prescribe tranexamic acid
Urgent referral to ENT – always have low suspicion for post-op tonsillectomy hemorrhage esp. in kids!
FeverPAIN criteria or Centro
Offer antibiotics:
feverpain score 2 or 3
Centor 3 or 4
FeverPAIN

- Attending early (within 3 days)
- Inflamed tonsils
- No cough
Centor criteria
Fever over 38ºC
Tonsillar exudates
Absence of cough
Tender anterior cervical lymph nodes (lymphadenopathy)
Indications for ABx:
- Marked systemic upset
- RF Hx
- Increased risk from acute infection
- Centor/FEVER Pain score
- Unilateral peritonsillitis
- Give pen v or clarithro for 7-10d
Red flags/complications of tonsilitis
- Quinsy
- Tonsillitis
- Sinusitis
- Mastoiditis
- Otitis media
- Laryngitis
- Scarlet fever, RF
- Lemierre’s syndrome
- Epiglottitis
which antibiotics for tonsilitis
Penicillin V (also called phenoxymethylpenicillin) for a 10-day course is typically first-line. It has a relatively narrow spectrum of activity and is effective against Streptococcus pyogenes.
Clarithromycin is the usual first-line choice in true penicillin allergy.
bacterial causes of sore throat
The most common cause: group A streptococcus (Streptococcus pyogenes). This can be effectively treated with penicillin V (phenoxymethylpenicillin).
The second most common bacterial cause of tonsillitis is Streptococcus pneumoniae.
Other causes:
Haemophilus influenzae
Moraxella catarrhalis
Staphylococcus aureus
summary of acute sore throat
Classic exam question: if give amox/ampicillin & develops macpap rash, think:
EBV
a maculopapular, pruritic rash develops in around 99% of patients who take ampicillin/amoxicillin whilst they have infectious mononucleosis
-> avoid contact sport for 6-8 weeks due to splenomegaly
Tonsillectomy Criteria:
Recurrent infection*…
* 7 ep. in 1 year
* 5 ep. for 2 years
* 3 ep. for 3 years
* Disabling & prevent normal functioning
Suspected malignancy
PSA/sleep disordered breathing in children
Recurrent quinsy
Severe immune deficiency
types of post-op tonsillectomy bleeds
Primary (<24hours)
Inadequate haemostasis
Secondary (>24 hr, usually 4-9d post-op)
Unclear aetiology – infection, fibrin clots, technique
management of post tonsillectomy bleed
Mx:
Always admit of Hx of blood
ABC + other measures
Examine throat
NOTIFY ENT REG***, involve paeds/anaesthetics early
A 59-year-old diabetic man sees his GP due to pain in his left ear. It has been there for the past 6 weeks, but in the last 2 weeks, he has been having ‘smelly white stuff’ coming out of his ear. He also complains about a headache around his left temporal area for the last few weeks not relieved by paracetamol.
On examination, he is apyrexial and neurological examination is normal. There is some creamy discharge in his left ear and on otoscopy, the walls are erythematous and sloughy. The tympanic membrane is normal.
Given the likely diagnosis, which of the following antibiotics will provide the best cover for the likely causative agent?
Amoxicillin
Gentamicin
Ciprofloxacin
Flucloxacillin
Metronidazole
Ciprofloxacin – OE in old diabetics → cover for Pseudomonas
otitis externa summary
History
- otalgia, pruritus, otorrhoea
Causes
- P.aueroginosa, S.aureus, candida, aspergillus
- moisture, trauma, absence of wax, dermatitis, swimming, hearing aids
Management
* Aural toilet (hoover out debris)
* ABx + steroid drops e.g. gentamicin
* KEEP EAR DRY
Necrotising/malignant OE
Temportal+ base of skull osteomyelitis - spread via the osseocartilaginous junction
- P.aueroginosa
Be aware the: diabetic, immunocompromised, elderly
Suspicious features
- Deep-seated pain, out of proportion
- Granulations
- Non-resolving OE
Other symptoms
- dysphagia
- hoarsness
- facila nerve dysfunction
Management
- admission
- CT scan
- IV abx e.g. ciprofloxacin
Complications
- Sinus thrombosis
- Meningitis
- Cerebral abscess
A 30yro woman presents to her GP with dizziness, nausea, and unilateral hearing loss which has been consistent for the past 2 days. Upon questioning, she denies having ever experienced symptoms like this before. She reports no tinnitus, otalgia or otorrhoea.
Upon examination, she is afebrile and does not appear to be in pain. Examination of her ears shows no abnormalities.
What is the most likely diagnosis?
Meniere’s disease
Benign Paroxysmal positional vertigo
Otitis media
Acute Labyrinthitis
Vestibular Neuronitis
Acute Labyrinthitis – pt has hearing loss + prolonged/constant vertigo
This patient has presented with symptoms of nausea, dizziness, and hearing loss. The likely diagnosis is labyrinthitis due to hearing loss. Labyrinthitis is inflammation of the labyrinth of the inner ear and presents with these symptoms and a sensorineural hearing loss.
acute lab vs vest neuronitis
Vestibular neuronitis is an inflammation of the eighth cranial nerve and presents similarly to labyrinthitis, however, it can be distinguished from the condition by the fact that vestibular neuronitis does not cause hearing loss.
